AlR-SEPARATOR FOR HYDRAULIC SYSTEMS.

SPECIFICATION forming part of Letters Patent No. 580,169, dated April 6,1897. Application filed October 15, 1895- Serial No. 565,812. (Nomodel.)

To all whom it may concern:

Be it known that 1, WILLIAM DEH. WASH- INGTON, of New York city, in thecounty of New York and State of New York, have in- 5 vented sundry newand useful Improvements in Air-Separators for Hydraulic Syste'rns, ofwhich the following, taken in connection with the accompanyingdrawings,is a specification.

This invention relates to air-separators; and it consists of certainimprovements in the construction thereof, as will be hereinafter fullydescribed, and pointed out in the specification and claims annexedthereto.

This invention is illustrated in the accompanying drawings, as follows:

Figure 1 is a vertical section on the line 2 2 in Fig. 2. Fig. 2 is avertical section on the line 1 1 in Fig. 1. Fig. 3 is a verticalelevation of one of the separating or stirring pipes with itsaccompanying fingers.

This device consists of a tapering shell or case A, having aninlet-opening a and an outlet-opening 6, larger than its inlet, theridges or riftles O, the depending vanes or wings D, and the air-openingd d, &c., the collecting-chamber B, and the separating or stirring pipesK, provided with the fingers k. Preferably these parts, with theexception of the separating pipes or fingers, are cast integral with thecase A, as shown, but not necessarily so. This tapering shell or case isconnected by its larger end to a settlingchamber E, which may be of theform shown or of any other preferable form. This settling-chamber isprovided at or near its bottom part with an outlet 6 to the hydraulicmachinery with which it is to be connected. The inlet-opening from thetaper-case A is preferably so located as to have the horizontal centerof the clear opening between the top of the rifiies O and the bottom ofthe wings D slightly above the top of the opening e, above referred to.The upper part of this chamber E is prolonged to. a sufficient height soas to form an airreservoir for holding the accumulated air brought to itby means described farther on until it can be properly drawn olf oremptied through the opening e, preferably located near the top of 0 thischamber. At or near its top is a manhole provided with a flange cover,to which may be connected the air-pipes f, which will be describedfarther on. The smaller end of the tapering case A is connected to thesuction-pipe B. At some point in the upper surface of this suction-pipeF, preferably a distance equal to two or three diameters of this pipe,may be located one or more wings or vanes D, depending from its uppersurface and which may be inserted therein or cast integral therewith.The lower edges of these wings or vanes, both those located in thesuction-pipe F and those in the taper-case A, before referred to, curvetoward the direction from which the liquid being handled is approaching.At the highest point in the upper surface of this suction-pipe F and thecase A, before referred to, and on the side of these vanes or wings nextto that from which the liquid being handled is approaching are holes dd, &c. These holes are connected to vertical air-pipes g g, &c., risingto a height equal to the top of the settling-chamber E. All of thesevertical pipes g g, &c., are joined to and connected with a horizontalpipe f, which is preferably connected to the flange on the top of thesettling-chamber E. Located near the smaller end of the tapercase A area number of small pipes K, provided with the fingers 7c and having theinlet openings j on the opposite side from which the liquid beinghandled is approaching. The upper ends of these pipes K are connectedwith the chamber B, which is situated on top of the case A and which maybe cast integral with it or fastened to it by any suitable means. Fromthe highest point of this case or chamber B one of the vertical pipes gleads to the suction of an air-pump or other means of abstracting thegases, or it may be connected to the horizontal pipe f, beforedescribed. The small fingers it project from opposite sides of thesepipes K and at right angles to the longitudinal axis of the case A.

0n the bottom surface of the tapering case or shell A are located ridgesor riffles O, which may be of any desired number. These riffles are ofsuch shape and are so located in reference to their corresponding vanesD that any air or other gas which may be contained in the liquid beinghandled is liberated by the eddy formed by such liquid in passing overthe riiiies O and is caught by the advancing edges of the vanes D.

The tapering case or shell permits the volume of water to expand as itenters the same and decreases its velocity, so that the gases containedtherein are readily liberated by the action of the ridges or riffleslocated in the shell, as the water when in its expanded state and underreduced velocity allows the gases to escape more readily than otherwise.

The action of this apparatus is as follows: Any air or other gas whichmaybe contained in the liquid being handled is first caught by theadvancing edges of the vanes D in the suction-pipe F. Any further gaseswhich pass these first vanes are liberated and separated by the fingers7c, projecting from the pipes K, and may pass up through the openings jin these pipes and be collected in the chamber B, or may be liberated bythe eddy formed by the riffles 0, just described, and be caught by theadvancing edges 'of the succeeding vanes D, projecting from the top ofthe case A, passing up on the upstream side of same and conducted by thepipes g g, &c., to the pipe f and thence to the suction-chainber E.

Having fully described my invention, what I desire to claim and secureby Letters Patent is as follows:

1. In the suction of ahydraulic apparatus, a tapering section or shellprovided in its lower portion with means for producing eddies in theliquid being handled, vanes on the upper portion of said section abovesaid means .to arrest the passage of the gases so liberated, and meanscommunicating with the upper portion for conveying such gases to areservoir, substantially as described.

2. In the suction of a hydraulic apparatus, the combination of atapering shell or section, riflies rising from the lower portionthereof, depending vanes above said rifiies, and means communicatingwith said section or shell adjacent to said vanes for conveying thegasesliberated to a reservoir, substantially as described.

3. In the suction of a hydraulic apparatus, the combination of a sectionor shell provided with depending collecting-pipes, means for agitatingthe liquid handled to liberate the gases therefrom, and conducting pipesin communication with said collecting-pipes and adapted to convey thegases therefrom, substantially as described.

at. In the suction of a hydraulic apparatus, the combination of asection or shell provided with riflies upon its lower surface, dependingvanes extending downward above said riflies,

conducting-pipes communicating with the upper portion of the section orshell between said vanes, and a reservoir having said conducting-pipescommunicating therewith substantially as described.

5. In the suction of a hydraulic apparatus,

the combination of a suction-pipe provided with gas-collecting vanes atthe upper portion thereof, an expanding section or shell provided withriftles upon its lower surface and collecting-vanes above said riflies,a settling-chamber in communication with the expandd end of said sectionor shell, and a gasconducting pipe communicating with the upper portionof said settling-chamber and with the upper portions of said expandingsection or shell and suction-pipe, substantially as described. p

6. In the suction of any hydraulic apparatus the combination of atapering section or shell, A, provided with the depending pipes, K,furnished with the fingers, k, for the put pose of liberating the gasesof the liquid being handled, the outlet-openings, d (1, d",

the collecting-chamber, B, the air-pipe, and air-pipe f and air-chamberE and means for abstracting the gases so collected, substantially asdescribed.

7. In the suction of any hydraulic apperatus the combination of atapering section, A, provided with the riffles, O, the depending pipes,K, the depending vanes, D, the outletopenings, cl d, &c., the air-pipes,g, g, 850., the air-pipe, F, and a settling-chamber, E, substantially asdescribed.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 1st day of October, A. D.1895.

WILLIAM DEH. WASHINGTON.
